130-135 dont matter, skill for skill prime for prime i dont think this fight has ever been mentioned before....
It would have been an interesting fight prime for prime at either weight like you said. Casa was not an easy fight for anyone but I'd expect Floyd to edge it out. Casa almost always came up short against the other elites, Castillo, Freitas (probably his absolute prime), 1 loss to Chico, Ko'd by Marquez (although he was way past his prime). His fans try to say he was cheated against all those guys but I agreed with all the decisions and if he struggled with them he would definatly struggle with Floyd.
Good fight. I say Floyd wins but not in dominate fashion. Casa is tricky and elusive. But I think Casa has poor balance b/c his mind moves faster than he feet and body allow. It would not be fan friendly though.
Would of been a great 1! I think Casamayor is technically above Chop Chop and Zab Judah. I deff don't count out the Cuban, I actually give him the edge because of his physical nature and great southpaw boxing skill. He's more mentally durable than Zab and is more composed than the two somewhat high-profile southpaws the P4P king faced.
At 130, I see PBF stopping him late. I thought this fight should have happened back then. Were they not champions at 130 at the same time or did they just miss each other? PBF; WBC, Frietas; WBO; Casa; I believe the IBF, and Chico; WBA. All I know is there was some good talent back then and props to Casa, PBF, Chico, and Freitas to fight each other back then.
